Specification of Letters Patent. Patented Mar. 30, 1920.

i Application filed April 25, 1916. Serial No. 93,404.

To all whom it may concern:

Be it known that I, WILLIAM L. PAUL, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Cultivators of which the following is a specification, reference being had therein to the accompanying drawing. A 7

My invention relates to cultivators, more particularly of the two-row type, and has for its object the construction and operation of certain mechanism by which the direction of travelof the machine can be controlled to suit varying conditions of cultivation; also to means by the operation-of which the gangs of cultivating devices can be adjusted laterally orlifted out of an operative position;

Referrin to the drawings in which similar numera ls indicate identical parts- Figure 1 is a plan view of a two row cultivator embodying my invention.

Fig. 2 is an end elevation. of Fig. 1' with the wheels removed.

Fig. 3 is an enlarged detail of the gang shifting mechanism, and

Fig. 4 is a rear view of one end of the cultivator.

The main frame consists of a front bar 1 and a rear bar 2 bent at their ends and secured together by castings 3 securely bolted thereto. Preferably integral with the castings 3 are vertical bearings 4 in which are journaled spindle ends of crank axles 5 which extend rearwardly of the main frame and have their terminations bent laterally to form stub axles bnwhich are supportin wheels-6. A seat support, having a seat on the rear end thereof, comprises parallel bars 8 and 9 spaced apart and pivotally supported on the frame .in the following mannerz Midway the length of the frame .bar 1 is securely bolted a bracket 10 having rearwardly extending parallel arms 11 and 12; braces 13 and 14 are secured to the bars 8 and 9 respectively-"and project forwardly and upwardly, beneath the arm 11, supporting a casting 15;"a V-shaped brace-16 isv low the latter to receive a casting 18 to -irrnn STATES PATENT orrion which the forward ends of theseat bars 8 and 9 are secured; the castings 15 and 18 are free to turn on the kingbolt 17 so that the seat support can be swung laterally-"in cal stud or pin 21 on which is loosely mounted a sleeve 22 having preferably integral therewith a horizontal sleeve 23; securedmidway its length in the sleeve 23 is a rod 24 having its ends hooked to engage with the rearward ends of arms 25 rigidly mounted on the upper endsof the spindles.

The rigs of cultivating devices are ar ranged in pairs and comprise bars 26 and 27 secured together at their rear ends, and connected at their forward ends to couplings 28 having sleeves 29 which are mounted on the horizontal ends of yokes 30. Between the sleeves 29 on each of the ends of the yokes 30 are collars 31 having eyes 32; braces 33 are pivotally secured to the frame bar 2 and extend forwardly and downwardly toward the eyes 32; braces 34 are pivotally mounted on the frame bar 1 and have eyes in their lower ends which register with the eyes 32, through the eyes on the braces 34 and the lower ends of the braces 33 extend and are secured in place by cotters or pins as may be desired. The yokes 30 are vertically disposed, their upper horizontal portions 35 being loosely held in guides 36 secured to the frame bar 1. On the inner vertical portions of the yokes 30 are clips 37 to which are connected links 38 and 38 extending toward the center of the cultivator. r Y

Secured between the bars 8 and 9 of the seat support, and preferably central of the main frame, is a member 39 having a downwardly extending spindle 40 on which is pivotally mounted bell cranks 41 and 42 so that their lateral arms 43 extend in opposite directions, and their forwardly extending arms 44 are parallel, the forward end of the arm. 44.0f the bell crank 41 beingpivotally connected to the link 38, and the end of the arm 44 of the bell crank 42 pivotally con neoted to the 1iI1k3 V Pivotally mounted intermediate its ends on the seat support is a manually operable lever provided with the usual type of latch to engage with notchesin a rack bar 46 secured on the seat support. To the lower end of the lever 45 is connected a rod 47 which extends forwardly and is hooked to the arm 43 of the bell crank 42, and a similar rod 48 connects the lever 45 with the arm 43 of the bell crank 41. By the con-' other through the links 38 which are connected thereto and to the bell cranks 41 and 42, the yokeshaving a swinging movement on the braces 33 and 34, pivoted on the main frame and by which the yokes 35 are supported. r

. The cultivating rigs are raised independently or simultaneously, asmay be desired, inthe following manner; journaled in suitable bearings on the frame bar 2, and adjacent the ends of the main frame, are rock shafts 49 and 50 having on their outer ends forwardly extending arms 51 which are connected to links 52, the latter connected at their lower ends to the outer cultivating rigs.

The inner ends of the rock shafts 49 and 50 have arms 53 on which are rigidly mounted hand levers 54. Between the rock shafts 49 and 50 and in alinement therewith and j ournaled in suitable bearings on the frame bar 2, is a rock shaft 55 on one end of which isv a master lever 56 provided with the usual form of latch to engage with notches in a segmental rack 57 mounted on the main frame; loosely mounted on the rock shaft '55 near the ends thereof, are levers 58 provided with forwardly extending arms 59 to which are connected links 60 having their lower ends attached to the inner cultivating rigs. Secured to the master lever 56 and on one side thereof a segment 61 having notches with which a latch on the lever 54 engages, and secured to the opposite side of the master lever 56 is a similar segment 62 having notches with which 'a latch on the adjacent lever 58 engages.

At the opposite end of the rock shaft 55 and mounted thereon are segments 63 and 64, the adjacent lever 58 having a latch of the usual'type to engagewithnotches on the segment'63, and the lever 54 having a similar latch to engage with notches in the segment 64. By the mechanism just described it is apparent that each cultivating rig can be raised at will, independently of the others, by actuating the lever to which it is connected and if it is desired to raise all the rigs simultaneously it can be readily done by means of the master lever {56, The rigs are In adjusting the wheels angu'larly theoperator with his feet upon'the treadles 66 on the inner rigs swings the seat support on its pivot 17 in the desired direction, and as the rod24 is connected to the seat support and to the arms 25 on the spindles of the crank axles 5 they are moved simultaneously in the same direction, angling the wheels and at the same time moving the frame and connected rigs in the same direction; it will be noted in this connection that the pivot 17 and the pivotal connections of the links38 and 38 with the bell, crank arms 44 are in a direct vertical line, consequently any lateral movement of the frame, when the wheels are angularly adjusted, will not disturb the position of the rigs as itwas prior to such adjustment, and for the same reason the rigs can be adjusted independently or simultaneously at anytime.

What I claim is- 1. Ina cultivator having a frame, axles having vertical spindles journaled on the frame, said axles extending rearwardly. of the frame and having wheels on the rearward ends, a seat support mounted on the frame to swing laterally, gangs of cultivating devices supported on the frame, horizontally disposed arms rigidly mountedonsaid spindles and extending parallel to each other, means'connecting said arms and seat support whereby as the seat support "is swung laterally said spindles are rotated to angle the wheels relatively to the frame and gangs of cultivating devices moving simultaneously in the same direction, and means to move said gangs laterally independent of the movement of the frame.

2. In a cultivator having a frame, axle having vertical. spindles journaled on the frame, said axles extending rearWa-rdly of the frame and having wheels on the rearward ends, a seat support pivotally mounted on the frame to swing laterally, gangs of cultivating devices supported on the. frame,

means connecting said seat support and spindles to actuate the latter by swinging the seat support to adjust the wheels angularly to the frame, the frame and gangs of cultivating devices moving simultaneously in the same direction, and means to move said gangs laterally independent of the movement of the frame.

3. Ina cultivator having a frame, axles having vertical spindles j ournaled on the frame, said axles extending rearwardly of the frame and having wheels on the rearward ends, a seat support pivotally mounted on the frame to swing laterally, gangsof cultivating devices supported on the frame, means connecting-"said seat support: and

spindles to actuate the latter by swinging the seat support to adjust the Wheels angularly to the frame, the frame and gangs of cultivating devices moving simultaneously in the same direction, and means on the seat support operable to move said gangs laterally independent of the movement of the frame.

In testimony whereof I affix my signature.

in presence of two Witnesses.
